Book Synopsis Solving Network Design Problems via Decomposition, Aggregation and Approximation by : Andreas Bärmann
Download or read book Solving Network Design Problems via Decomposition, Aggregation and Approximation written by Andreas Bärmann and published by Springer. This book was released on 2016-06-02 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Andreas Bärmann develops novel approaches for the solution of network design problems as they arise in various contexts of applied optimization. At the example of an optimal expansion of the German railway network until 2030, the author derives a tailor-made decomposition technique for multi-period network design problems. Next, he develops a general framework for the solution of network design problems via aggregation of the underlying graph structure. This approach is shown to save much computation time as compared to standard techniques. Finally, the author devises a modelling framework for the approximation of the robust counterpart under ellipsoidal uncertainty, an often-studied case in the literature. Each of these three approaches opens up a fascinating branch of research which promises a better theoretical understanding of the problem and an increasing range of solvable application settings at the same time.
Book Synopsis Telecommunications Network Planning by : Brunilde Sansò
Download or read book Telecommunications Network Planning written by Brunilde Sansò and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Telecommunications - central to our daily lives - continues to change dramatically. These changes are the result of technological advances, deregulation, the proliferation of broadband service offers, and the spectacular popularity of the Internet and wireless services. In such adynamic technological and economic environment, competition is increasing among service providers and among equipment manufacturers. Consequently, optimization of the planning process is becoming essential. Although telecommunications network planning has been tackled by the Operations Research community for some time, many fundamental problems remain challenging. Through its fourteen chapters, this book covers some new and some still challenging older problems which arise in the planning of telecommunication networks. Telecommunications Network Planning will benefit both telecommunications practitioners looking for efficient methods to solve their problems and operations researchers interested in telecommunications. The book examines network design and dimensioning problems; it explores Operation Research issues related to a new standard Asynchronous Transfer Mode (ATM); it overviews problems that arise when designing survivable SDH/SONET Networks; it considers some broadband network problems; and it concludes with three chapters on wireless and mobile networks. Leading area researchers have contributed their recent research on the telecommunications and network topics treated in the volume.

This book was released on 1998 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: LE TRAVAIL DE CETTE THESE PORTE SUR LA CONCEPTION D'ALGORITHMES PARALLELES POUR LA RESOLUTION DE DEUX CLASSES DE PROBLEMES D'OPTIMISATION DANS LES GRAPHES : LES PROBLEMES DE FLOT DE COUT MINIMUM A CRITERE CONVEXE ET LES PROBLEMES DE TYPE FLOT MAXIMUM/COUPE MINIMALE. IL CONCERNE EGALEMENT LA MISE EN UVRE DE CES ALGORITHMES SUR DES MACHINES PARALLELES A MEMOIRE DISTRIBUEE ET A MEMOIRE PARTAGEE. DANS LA PREMIERE PARTIE DU DOCUMENT, NOUS NOUS INTERESSONS AU PROBLEME DE FLOT DE COUT MINIMUM A CRITERE CONVEXE. LES METHODES DE GRADIENT ET DE RELAXATION PERMETTANT DE RESOUDRE CETTE CLASSE DE PROBLEME SONT PERFORMANTES ET BIEN ADAPTEES A UNE MISE EN UVRE PARALLELE. NOUS NOUS CONCENTRONS PRINCIPALEMENT SUR LES METHODES ITERATIVES PARALLELES DEPOURVUES D'UN CONTROLE DES ITERATIONS, APPELEES ITERATIONS ASYNCHRONES. APRES UN RAPPEL DE LEUR FORMULATION ET DE RESULTATS DE CONVERGENCE, NOUS PRESENTONS UNE EXTENSION OFFRANT UNE PLUS GRANDE SOUPLESSE DANS LA COMMUNICATION DES ITERES PARTIELS ENTRE LES PROCESSEURS : LES ITERATIONS ASYNCHRONES AVEC COMMUNICATION FLEXIBLE. NOUS VALIDONS CETTE NOUVELLE APPROCHE PAR L'EXPERIMENTATION SUR DEUX ARCHITECTURES PARALLELES : LE T-NODE (MEMOIRE DISTRIBUEE) AINSI QU'UN MULTIPROCESSEUR SUN SMP (MEMOIRE PARTAGEE). LA SECONDE PARTIE DU MEMOIRE EST CONSACREE AU PROBLEME DE FLOT MAXIMUM/COUPE MINIMALE, QUI EST UN CAS PARTICULIER DU PROBLEME DE FLOT DE COUT MINIMUM A CRITERE LINEAIRE. DANS UN PREMIER TEMPS, NOUS PRESENTONS LE PROBLEME AINSI QUE LES DEUX PRINCIPALES CLASSES D'ALGORITHMES SEQUENTIELS PERMETTANT DE LE RESOUDRE : LES ALGORITHMES BASES SUR UNE CHAINE AMELIORANTE ET CEUX BASES SUR LA NOTION DE PREFLOT. DANS UN SECOND TEMPS, NOUS COMPARONS LES PERFORMANCES DE CES ALGORITHMES POUR DES PROBLEMES DE TOPOLOGIE DIFFERENTE A PARTIR D'EXPERIMENTATIONS NUMERIQUES. NOUS PROPOSONS ENFIN UNE STRATEGIE DE PARALLELISATION DU PREFLOT PAR L'UTILISATION DE THREADS SUR ARCHITECTURE FAIBLEMENT PARALLELE.
Book Synopsis PROMOTION DE LA SANTE ET AUTONOMISATION DANS LE CONTEXTE AFRICAIN by : David HouŽto
Download or read book PROMOTION DE LA SANTE ET AUTONOMISATION DANS LE CONTEXTE AFRICAIN written by David HouŽto and published by Lulu.com. This book was released on 2014-02-26 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le terme promotion de la santé en Afrique, près de 30 ans après l'adoption de la Charte d'Ottawa, continue d'avoir des connotations complètement hors du sens que lui confère cette charte. Cela n'est pas étonnant quand on sait que la notion de santé dans ce contexte africain équivaut à la lutte contre la maladie à travers les soins de santé dispensés par des professionnels de la santé dans des formations sanitaires et les hôpitaux. L'évolution que connait le continent depuis quelques décennies est de donner un peu plus de place à la communauté à travers les relais communautaires dans une participation communautaire vidée de son contenu, car le pouvoir n'est jamais passé entre les mains des communautés.C'est au vu de tout ceci que le présent ouvrage à sa raison d'être pour expliquer les fondements de l'autonomisation communautaire et de la promotion de la santé avec leur importance pour la région africaine en proie aux mauvais indicateurs de santé comparativement aux autres régions du monde.

Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Book Synopsis Cambridge Handbook of Engineering Education Research by : Aditya Johri
Download or read book Cambridge Handbook of Engineering Education Research written by Aditya Johri and published by Cambridge University Press. This book was released on 2014-02-10 with total page 1124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambridge Handbook of Engineering Education Research is the critical reference source for the growing field of engineering education research, featuring the work of world luminaries writing to define and inform this emerging field. The Handbook draws extensively on contemporary research in the learning sciences, examining how technology affects learners and learning environments, and the role of social context in learning. Since a landmark issue of the Journal of Engineering Education (2005), in which senior scholars argued for a stronger theoretical and empirically driven agenda, engineering education has quickly emerged as a research-driven field increasing in both theoretical and empirical work drawing on many social science disciplines, disciplinary engineering knowledge, and computing. The Handbook is based on the research agenda from a series of interdisciplinary colloquia funded by the US National Science Foundation and published in the Journal of Engineering Education in October 2006.

Book excerpt: This report reviews engineering's importance to human, economic, social and cultural development and in addressing the UN Millennium Development Goals. Engineering tends to be viewed as a national issue, but engineering knowledge, companies, conferences and journals, all demonstrate that it is as international as science. The report reviews the role of engineering in development, and covers issues including poverty reduction, sustainable development, climate change mitigation and adaptation. It presents the various fields of engineering around the world and is intended to identify issues and challenges facing engineering, promote better understanding of engineering and its role, and highlight ways of making engineering more attractive to young people, especially women.--Publisher's description.
Book Synopsis Faecal Sludge Management by : Linda Strande
Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.
Book Synopsis Decentralised Internet of Things by : Mohammad Ayoub Khan
Download or read book Decentralised Internet of Things written by Mohammad Ayoub Khan and published by Springer. This book was released on 2020-02-14 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents practical as well as conceptual insights into the latest trends, tools, techniques and methodologies of blockchains for the Internet of Things. The decentralised Internet of Things (IoT) not only reduces infrastructure costs, but also provides a standardised peer-to-peer communication model for billions of transactions. However, there are significant security challenges associated with peer-to-peer communication. The decentralised concept of blockchain technology ensures transparent interactions between different parties, which are more secure and reliable thanks to distributed ledger and proof-of-work consensus algorithms. Blockchains allow trustless, peer-to-peer communication and have already proven their worth in the world of financial services. The blockchain can be implanted in IoT systems to deal with the issues of scale, trustworthiness and decentralisation, allowing billions of devices to share the same network without the need for additional resources. This book discusses the latest tools and methodology and concepts in the decentralised Internet of Things. Each chapter presents an in-depth investigation of the potential of blockchains in the Internet of Things, addressing the state-of-the-art in and future perspectives of the decentralised Internet of Things. Further, industry experts, researchers and academicians share their ideas and experiences relating to frontier technologies, breakthrough and innovative solutions and applications.
